Forest development stages ^(Jeschke) Loss of final stage

Most of forest associations in Central Europe, described by phyto-sociology are degradation stages, or pioneer / intermediate stages of forest development

In functional restoration programs studying of old-growth (OG) stands

and historical landscapes is key to describing the reference conditions

associated with to natural forest ecosystems.
